History: 78 yo male with prior history significant for squamous cell carcinoma (T1N0M0) of the true vocal cord 20 years prior now with loss of hearing in the left ear for several months

Findings: Large tumor of the left vascular space which displaces adjacent vessels. Condylar and basilar portions of the occipital bone are eroded. The lesion is slightly hypointense to gray matter on T1 and vigorously enhances following contrast administration. A salt and pepper appearance is noted.

MPX1736_synpic19972: Pre and post gadnolinium administration shows predominately marked enhancment with scattered foci of non-enhancment (salt and pepper). Occipital and basilar bony erosion is again noted. The mass begins superiorly at the posterior margin of the anterior canal of the occipital condyle and extends inferiorly to approximately the level of the carotid bulb at C2.
